ALSA sync issues with 12in Powerbook G4

[Myo <myosrcgz@gmail.com>]

hello list, 

I've just done a testing/Lenny install on a 12in Powerbook G4 1.33ghz with a "snapper" soundcard. everything seems ok, except that I get A/D/A sync errors when using ALSA as the driver for audio apps. after googling around I see that this is a not-too-uncommon issue? is there a way to resolve this? I'm not a total nub, but I don't know anything about configuring ALSA on gut level, so any advice would be very appreciated. 

thanks alot
